Description

Technical Field

[0001] This utility model relates to the field of encoder test bench technology, and in particular to encoder test bench. Background Technology

[0002] In the field of encoder testing, existing encoder testing equipment typically relies on the rotation mechanism of the spindle under test for detection. When the spindle sent for repair by a customer is jammed, the encoder wheel cannot rotate normally with the spindle. This prevents traditional testing equipment from independently completing encoder performance testing without the original spindle, requiring a significant amount of time to disassemble or repair the spindle before testing can begin, severely impacting repair efficiency. Therefore, this platform is designed to accurately perform encoder testing even when detached from the original spindle. Furthermore, existing equipment has the following drawbacks during encoder installation:

[0003] Staff need to manually adjust the position of the encoder on the mounting base, which makes it difficult to quickly align it to the center, resulting in a long installation time and low efficiency, especially in batch testing scenarios.

[0004] Rotating components (such as encoder wheels) are exposed, posing a risk of finger contact during manual operation and presenting significant safety hazards.

[0005] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when installing the first encoder, the operator cannot accurately place the first encoder in the center of the encoder mounting base, which results in the operator having to spend a long time installing the first encoder, thus causing the operator's installation efficiency to be low; therefore, an encoder test bench is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty for workers to accurately place the first encoder in the center of the encoder mounting base, which leads to a long installation time and low installation efficiency. The proposed encoder test bench is designed to address these issues.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an encoder test bench, comprising a housing, a support frame mounted on the surface of the housing, an encoder mounting base mounted on the surface of the support frame, a first encoder mounted on the surface of the encoder mounting base, a code wheel mounting base mounted on the surface of the housing, an encoder wheel mounted on the surface of the code wheel mounting base, a bearing mounted inside the housing, a shaft mounted inside the housing, a locking nut mounted on the surface of the shaft, two fixing plates fixedly connected to the surface of the encoder mounting base, two springs fixedly connected to one side of each fixing plate, and a limit plate fixedly connected to the end of each spring away from the fixing plate.

[0008] The effect achieved by the above-mentioned components is to restrict the movement of the first encoder, thus preventing the operator from failing to accurately place the first encoder in the center of the encoder mounting base during installation, which would otherwise require a long time to install and result in low installation efficiency. This improves the operator's installation efficiency.

[0009] Preferably, protective pads are slidably connected to the sides of the two limiting plates that are close to each other, and the size of the protective pads is adapted to the size of the limiting plates.

[0010] The effect achieved by the above components is that the protective pad can protect the first encoder and avoid the limit plate from making hard contact during the long-term clamping of the first encoder, which could easily damage the first encoder.

[0011] Preferably, the limiting plate has two screws threaded into its internal threads, and one end of each screw is rotatably connected to the protective pad.

[0012] The above-mentioned components achieve the following effect: they facilitate workers to quickly replace the protective pads, avoiding the situation where workers have difficulty replacing the protective pads after they are damaged, which would reduce the protective effect of the pads.

[0013] Preferably, a sliding rod is slidably inserted into the fixed plate, and one end of the sliding rod is fixedly connected to the limiting plate.

[0014] The effect achieved by the above components is that the sliding rod can limit the movement path of the limiting plate and prevent the limiting plate from deviating during movement.

[0015] Preferably, two protective shells are slidably connected to the surface of the housing, a square block is fixedly connected to the arc surface of the protective shell, a connecting rod is fixedly connected to the surface of the square block, a connecting plate is fixedly connected to one end of the connecting rod, two insert rods are slidably inserted into the connecting plate, and four slots are opened on the surface of the housing.

[0016] The aforementioned components achieve the following effect: they protect workers by preventing them from touching rotating parts with their fingers during manual operation, thus preventing injury and improving the safety of the equipment.

[0017] Preferably, the connecting rod is rotatably connected to a blocking plate on its arc surface, and the surface of the blocking plate is provided with a blocking groove.

[0018] The effect achieved by the above components is that the baffle plate can restrict the movement of the insertion rod, preventing the insertion rod from slipping and colliding with the shell when the staff moves the protective shell, thus avoiding damage to the insertion rod.

[0019] Preferably, a blocking block is fixedly connected to the surface of the square block, and a torsion spring is sleeved on the arc surface of the connecting rod, with the two ends of the torsion spring being fixedly connected to the connecting plate and the blocking plate, respectively.

[0020] The effect achieved by the above components is that the torsion spring's torque automatically rotates the stop plate back, reducing the number of steps required by the operator, allowing them to proceed to the next step more quickly, and improving their work efficiency.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] 1. In this utility model, the movement of the first encoder is restricted, which avoids the situation where the first encoder cannot be accurately placed in the center of the encoder mounting base when the operator is installing it, thus avoiding the situation where the operator needs to spend a long time installing the first encoder and resulting in low installation efficiency. This improves the operator's installation efficiency. Attached Figure Description

[0031] Reference Figures 1-7As shown, this utility model provides a technical solution: an encoder test bench, including a housing 6, a support frame 5 mounted on the surface of the housing 6, an encoder mounting base 4 mounted on the surface of the support frame 5, a first encoder 1 mounted on the surface of the encoder mounting base 4, a code wheel mounting base 3 mounted on the surface of the housing 6, an encoder wheel 2 mounted on the surface of the code wheel mounting base 3, a bearing 21 mounted inside the housing 6, a shaft 22 mounted inside the housing 6, a locking nut 23 mounted on the surface of the shaft 22, two fixing plates 7 fixedly connected to the surface of the encoder mounting base 4, two springs 8 fixedly connected to one side of the fixing plate 7, and a limit plate 9 fixedly connected to the end of the two springs 8 away from the fixing plate 7, thereby achieving the limitation. The movement of the first encoder 1 prevents workers from failing to accurately place the first encoder 1 in the center of the encoder mounting base 4 during installation, thus avoiding the time-consuming and inefficient installation process. Protective pads 10 are slidably connected to the sides of the two limiting plates 9 that are close to each other. The size of the protective pads 10 matches the size of the limiting plates 9. When the worker needs to install the first encoder 1, the limiting plates 9 are moved first, causing the protective pads 10 to move. At this time, the spring 8 is compressed. When the limiting plates 9 move to the appropriate position, the first encoder 1 is placed on the surface of the encoder mounting base 4. The limiting plates 9 are then released. The rebound force of spring 8 drives the limiting plate 9 to move, and the limiting plate 9 drives the protective pads 10 to move until both protective pads 10 contact the surface of the first encoder 1. At this time, the first encoder 1 is in the center of the encoder mounting base 4, and the operator can install the first encoder 1. The protective pads 10 achieve the effect of protecting the first encoder 1, avoiding hard contact between the limiting plate 9 and the first encoder 1 during long-term clamping, which could easily damage the first encoder 1. Two screws 11 are inserted into the internal thread of the limiting plate 9. One end of the screw 11 is rotatably connected to the protective pad 10. When the protective pad 10 is damaged after long-term use, the operator can replace the protective pad 10 by rotating the screw 11 until one end of the screw 11 is completely removed from the surface of the first encoder 1. When the protective pad 10 detaches from the surface, the screw 11 releases its fixation, allowing the protective pad 10 to move and slide on the surface of the limiting plate 9. When the protective pad 10 is completely detached from the surface of the limiting plate 9, the protective pad 10 is disassembled. At this point, the worker can place a new protective pad 10 on the surface of the limiting plate 9 and rotate the screw 11. When the screw 11 rotates into the protective pad 10, it can fix the protective pad 10 in place. This completes the replacement of the protective pad 10, achieving the effect of facilitating quick replacement by the worker and avoiding the situation where the protective pad 10 is damaged and difficult to replace, resulting in a reduction in its protective effect. A sliding rod 12 is slidably inserted into the fixing plate 7, with one end of the sliding rod 12 fixedly connected to the limiting plate 9.When the operator moves the limiting plate 9, the limiting plate 9 moves the protective pad 10, compressing the spring 8. The limiting plate 9 then moves the sliding rod 12 until the limiting plate 9 reaches the appropriate position. The sliding rod 12 effectively restricts the movement path of the limiting plate 9, preventing it from shifting during movement. Two protective shells 13 are slidably connected to the surface of the housing 6. A square block 14 is fixedly connected to the arc surface of the protective shell 13. A connecting rod 15 is fixedly connected to the surface of the square block 14. A connecting plate 16 is fixedly connected to one end of the connecting rod 15. Two insert rods 17 are slidably inserted into the connecting plate 16. Four slots are provided on the surface of the housing 6. When the operator needs to rotate the encoder wheel 2, the protective shell 13 can be moved to... Directly below the encoder wheel 2, pull the insertion rod 17. When the insertion rod 17 is completely disengaged from the surface of the slot in the housing 6, move the protective shell 13. The protective shell 13 moves the square block 14. When the protective shell 13 moves to the appropriate position, push the insertion rod 17. When the insertion rod 17 is inserted into the surface of the slot in the housing 6, the insertion rod 17 can fix the protective shell 13. At this time, the operator can rotate the encoder wheel 2, achieving the effect of protecting the operator and preventing the operator's fingers from contacting the rotating parts during manual operation, thus improving the safety of the equipment. The arc surface of the connecting rod 15 is rotatably connected to the blocking plate 18. The surface of the blocking plate 18 has a blocking groove. When the operator needs to move the protective shell 13, Pull the insertion rod 17. When the insertion rod 17 is completely disengaged from the surface of the slot in the housing 6, rotate the blocking plate 18. When the blocking plate 18 is rotated to the appropriate position, the insertion rod 17 is directly above the blocking groove of the blocking plate 18. Push the insertion rod 17 to insert it into the surface of the slot in the blocking plate 18. The blocking plate 18 can restrict the movement of the insertion rod 17. At this time, the operator can move the protective housing 13. The blocking plate 18 achieves the effect of restricting the movement of the insertion rod 17, preventing the operator from shaking the protective housing 13, causing the insertion rod 17 to slide, collide with the housing 6, and be damaged. The surface of the square block 14 is fixedly connected to the blocking block 19, and the arc surface of the connecting rod 15 is also fixedly connected to the square block 14. A torsion spring 20 is fitted, with its two ends fixedly connected to the connecting plate 16 and the blocking plate 18, respectively. When the operator moves the protective shell 13 to the appropriate position, they pull the insertion rod 17. When the insertion rod 17 completely disengages from the surface of the blocking groove on the blocking plate 18, the torque of the torsion spring 20 causes the blocking plate 18 to rotate. When the blocking plate 18 contacts the surface of the blocking block 19, it stops moving. At this point, the operator can insert the insertion rod 17 into the surface of the slot on the shell 6. The insertion rod 17 then secures the protective shell 13. The torque of the torsion spring 20 achieves the effect of automatically rotating the blocking plate 18 back, reducing the operator's steps and allowing for faster progress, thus improving work efficiency.

[0032] Working principle: When the operator needs to install the first encoder 1, first move the limiting plate 9. The limiting plate 9 moves the protective pad 10, compressing the spring 8. The limiting plate 9 then moves the sliding rod 12. When the limiting plate 9 moves to the appropriate position, place the first encoder 1 on the surface of the encoder mounting base 4. Release the limiting plate 9. The rebound force of the spring 8 moves the limiting plate 9, which in turn moves the sliding rod 12, and finally the protective pad 10, until both protective pads 10 are in contact with the surface of the first encoder 1. At this point, the first encoder 1 is in the center of the encoder mounting base 4. The operator can then proceed as follows: The first encoder 1 can be installed. When the protective pad 10 is damaged after prolonged use, the operator can replace it. By rotating the screw 11, when one end of the screw 11 is completely detached from the protective pad 10, the screw 11 releases its fixation on the protective pad 10. The protective pad 10 is then moved, sliding on the surface of the limiting plate 9. When the protective pad 10 is completely detached from the surface of the limiting plate 9, the protective pad 10 is disassembled. At this point, the operator can place a new protective pad 10 on the surface of the limiting plate 9 and rotate the screw 11. When the screw 11 rotates into the protective pad 10, it can fix the protective pad in place. 10. At this point, the protective pad 10 has been replaced. When the worker needs to move the protective shell 13, pull the insertion rod 17. When the insertion rod 17 is completely disengaged from the surface of the slot in the shell 6, rotate the blocking plate 18. When the blocking plate 18 is rotated to the appropriate position, the insertion rod 17 is directly above the blocking groove of the blocking plate 18. Push the insertion rod 17 to insert it into the surface of the slot in the blocking plate 18. The blocking plate 18 can restrict the movement of the insertion rod 17. At this point, the worker can move the protective shell 13. After the worker moves the protective shell 13 to the appropriate position, pull the insertion rod 17. When the insertion rod 17 is completely disengaged from the blocking plate 18... When the surface of the blocking groove is reached, the torque of the torsion spring 20 drives the blocking plate 18 to rotate. When the blocking plate 18 contacts the surface of the blocking block 19, the blocking plate 18 stops rotating. The operator can then insert the insertion rod 17 into the surface of the slot in the housing 6. The insertion rod 17 can fix the protective housing 13. At this time, the movement of the first encoder 1 can be restricted, which avoids the operator not being able to accurately place the first encoder 1 in the center of the encoder mounting base 4 when installing the first encoder 1, which would cause the operator to spend a long time installing the first encoder 1, resulting in low installation efficiency.
